Recycle Segment #

Edit guarantee hold

This lets you specify the conditions under which a segment will GHOLD when deviation exceeds the
guarantee hold limits. If any setpoint's guarantee hold limit is exceeded, the entire schedule enters GHOLD
state (all setpoints, auxiliary setpoints, and segment events freeze on their current value or state) until none
of the limits are exceeded, whereupon the schedule will resume RUN state.

Guar Hold 1 through Guar Hold 8

Edit segment events

This lets you edit the state of up to 16 events for the selected segment. You can configure 1 to 16 segment
events to turn ON or OFF at the beginning of each segment. Segment events are digital switches that
provide ON/OFF outputs. When a segment event is turned ON, it remains ON until the end of the segment
at which time it is turned OFF unless it is configured to turn ON in the next segment.
TIP
Events can be edited only while schedule is in READY state.

Enter the amount of time for the segment to last (in Time Units shown).
Range 0-9999.
Enter the number of times a schedule is to be repeated. 1-999. 0=infinite.
Example:
Segment #30 has recycle count = 10 and recycle segment #5. Therefore,
the first time the schedule reaches Segment #30, the schedule will recycle
(repeat) Segments #5 through #30 ten times. During the first recycling, it
will display "10", during the second recycling it will display "9", etc.
Enter the segment number at which a recycle will start.
OFF: Segment will not GHOLD when the PV deviates from SP by its
guarantee hold limit.
HIGH: Segment will GHOLD if PV deviates above SP by more than the
SP guarantee hold limit.
LOW: Segment will GHOLD if PV deviates below SP by more than the SP
guarantee hold limit.
HIGH/LOW: Segment will GHOLD if PV deviates above or below SP by
more than the SP guarantee hold limit.
